论文摘要
阐明手性诱导的自旋选择性背后的机制仍然是一个杰出的科学挑战。在这里,我们考虑了DeLabalised声子模式在手性结构中电子传输中的作用,并证明自旋选择性可以起源于旋转依赖性能量和动量保存,而动量保存在电子 - 音波散射事件中。尽管这种机制对振动模式的特定性质是可靠的,但自旋极化程度取决于环境因素,例如外部驾驶场,温度和声子松弛率。这种依赖性用于介绍我们模型的实验测试预测。
The elucidation of the mechanisms behind chiral-induced spin selectivity remains an outstanding scientific challenge. Here we consider the role of delocalised phonon modes in electron transport in chiral structures and demonstrate that spin selectivity can originate from spin-dependent energy and momentum conservation in electron-phonon scattering events. While this mechanism is robust to the specifical nature of the vibrational modes, the degree of spin polarization depends on environmental factors, such as external driving fields, temperatures and phonon relaxation rates. This dependence is used to present experimentally testable predictions of our model.
